SAFETY aazon.

Application filed June 5,

To all whom it may concern:

Be it known that I, ISAK EKLUND, asubject of the King of Sweden, residing at Paterson, in the county of Passaic and State of New Jersey, have" invented new and useful, Improvements in Safety Razors, of

which the following is a specification.v

This invention relates to safety razors, and more particularly to the means whereby the blade is held in position for use, the object of the invention being to provide a holding means embodyin certain novel and im proved features of construction to be hereinafter'describedin detail, whereby a better securely held without the usual studs panying drawing, .wherein:

' with a blade-clamping cap removed;-Fig. 4

is a perspective view of the blade-clamping cap; Fig. 5 is .a plan view of the blade-supporting head; Fig. 6 is a front elevation,"

.teeth. .However, both edges may be made,

and Fig.- 7 is an enlarged cross-section of the'razor illustrating its operation.

Referring specifically to the drawing, the

holderfor the blade 10 comprises a handle 11, a blade-supporting head 12, and a bladeclamping cap 13. From the inner face of the cap 13 projects a threaded stud 14 which passes loosely through an aperture in the blade and an aperture 15 in the head for attachment to the handle 11, the latter having a threaded hole in its outer end to receive the stud. The blade 10 is positioned between the head 12 and the cap 13, and it is securely held clamped therebetween upon screwing the handle 11 on the stud 14. This is a well-known construction and a further description thereof is therefore not necessar X further means for holding the blade 10 in place between the head 12 and-the cap 13 consists in laterally projecting lugs 16 formed integral with the cap at the ends thereof, said lugs being rearwardl directed to seat in recesses 17 in the ends 0 the blade 10, and recesses 18in the ends of the head 12,

said recesses registering so that the lugs may enter the same, By providing these, lugs the blade is securely held, and the usual pins or studs on thecap passing through apertures in the blade and the head are dis- 1922. Serial No. 566,182.

pensed with. The absence of such a ertures in the blades materially strengthens t e same. It will also be noted by reference to Fig. 3 that the end recesses'l7 of the blade are rounded at their inner cornerswhich is done for the purpose of obtaining a more uniform temper.- Experiments have shown that a uniform and even temper is impossible to obtain where the recesses have sha corners, whereas with the corners rouii the blade is given a uniform temper throughoutitsentire area.

' The head 12 and the cap 13'have theusual transverse curvature in order to obtain the necessary flexure of the blade 10, and the width-of the head is also greater than that.

of the cap so that the longltudinal edges of I the head are located outwardly of the corresponding edges of the cap. The cutting edgesof the blade project slightly outward- 1y. from the longitudinal edges of the cap and Y terminate slightly to the rear of the. longitudinal edges ofthe head. One of the longitudinal edges of the head is provided with the usual row of teeth 19 whereas its other longitudinaledge is left plain and without plain and without teeth, or they may be given a toothed formation. The plain edge formation is the preferred structure as such an edge is in contact with the skin throughout the entire length of the blade, whereas with a toothed edge, the skin is engaged only at spaced points. The plain edge therefore .90 'rides over the face with greater ease, and

without any tendency to irritate the skin,

especially where the latter is tender.

The longijudinal plain edge of the head 12 has a projecting flange 20 which is rearward ly directed, and this flange is made 'by a rounded bend in the edge" portion of the.

head. This structure produces a rounded .and smooth surface in advance of the cutting edge of the blade, and as this surfaceengages the face when the razor is in use it slides easily and" smoothly over the same. Back of the flange 20,the Head 12 is formed with a depression 21 running in the direction of the length of they head and parallel to the flange. The blade 10 overhangs this depression. The purpose of this construction is to increase the "effectiveness of the cuttin action of the blade 10. Referring to Fig. ,it' will be noted that when the razor-is moved across the face in the 'direc- 3 tion of the arr-om the cutting edge of'the' blade behind the flanged edge portion of the head 12, and the latter bends the hairs down toward the skin. However, as soon as the hairs clear the flanged edge portion of the head, they rise so that they are. now squarely presented to the cutting edge of the blade, this action being permitted by the depression 21, the hairs swinging into the same to assume a more or less perpendicular position to the skin. The flanged edge portion of the head 12 is also so spaced from the edge of the cap 13, that when the razor is placed at such an angle to the face that the head and the cap are in contact therewith, the blade 10 will be at the most advantageous angle for cutting the beard. The flanged edge portion of the head, when drawn across the face, acts to draw the-skin tight in advance of the cutting edgeof the blade, whereby the hairs which project into the depression 21 are held erect so that they are easily cut when the cutting edge of the blade reaches the same. The action is in all respects similar to that of a barber drawing the skin tight in advance of. the razor.

The hereinbefore described arrangement of flange and depression is also employed in connection with the toothed or comb edge of the head 12. a r

At the ends of the flanged edge of the head 12 are slight protuberances or raised portions 22 behind which the cornersof the blade 10 seat'fiush therewith; as shown in Figs. 1 and 6, and said corners are also rounded off as shown in Fig. 3. By this construction sharp corners at the ends of the cutting edges of the blades are avoided, and at the same time said ends are not left exposed to cut or scratch the face. A safety razor constructed as herein-. before described is simple, and capable of being cheaply and easily manufactured and by its'use it is made possible to obtain a smooth shave without the least discomfort or irritation-where the skin is tender.

I claim:

1. A safety razor-comprising an elongated head having one longitudinal edge portion formed with a longitudinal depression and a rearwardly projecting flange, the flange being extended for the full length of said head and the depression terminating short of the ends of said head 'and the flange, whereby to define protecting members at the ends of the head, for the corners of the blade, a holder having an attaching member extending through said head and having its ends provided between its longitudinal edges with blade holding lugs, and a blade confined between said holder and head, the ends of said blade and the ends of said head being formed with notches snugly receiving said lugs whereby the blade and the holder are held in position, said flange being approximately in a plane at right angles to the normal plane of the blade.

2. A safety razor comprising an elongated head having one longitudinal edge portion formed with a longitudinal depression, a rearwardly projecting flange extending approximately in a plane akright angles to the normal plane of a blade supported on said head. the flange being extended for the full length of said head and the depression terminating short ofthe ends of said head and flange, whereby to define protecting members at the ends of the edge fpr the corners of the blade, a holder having an attaching member extending through said ISAK EKLUND.
